What is a “funnel” in Kanban?

In the Kanban Guide, we define Kanban. We bring Kanban down to the minimal aspects, and we hope you find that helpful.

In doing so, we made a lot of things optional. One of the things that is optional in the definition of workflow is a backlog. You do not have to have a backlog on a definition of workflow, and I wrote about defining your workflow in a previous article.

Funnel is another optional container, if you like, another piece of your workflow that you can have. If you did have a backlog, a funnel might be a backlog for a backlog.

So, it can be helpful in situations where you’ve got a roadmap, and maybe you’re doing something like now, next, or later.

• now → would be whatever is in progress;
• next → might be what is in the backlog (if you have a backlog); and
• later → might be what is after whatever is in the backlog.

Some might call it a hopper, a pool of ideas; whatever you want to call it is fine.
